Airworthiness Directives; Dornier

Model 328–100 Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Dornier Model

328–100 series airplanes, that requires a

one-time visual inspection to detect

cracking in the axle adapter of the shock

absorber of the nose landing gear (NLG),

and corrective actions, if necessary. This

amendment is prompted by issuance of

mandatory continuing airworthiness

information by a foreign civil

airworthiness authority. The actions

specified by this AD are intended to

correct cracking in the axle adapter of

the shock absorber of the NLG, which

could result in failure of the NLG and

consequent damage to the airplane

structure.

DATES: Effective August 12, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of August 12,

1998.

ADDRESSES: The service information

referenced in this AD may be obtained

from FAIRCHILD DORNIER, DORNIER

Luftfahrt GmbH, P.O. Box 1103, D–

82230 Wessling, Germany. This

information may be examined at the

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

that is applicable to certain Dornier

Model 328–100 series airplanes was

published in the Federal Register on

May 12, 1998 (63 FR 26112). That action

proposed to require a one-time visual

inspection to detect cracking in the axle

adapter of the shock absorber of the

nose landing gear (NLG), and corrective

actions, if necessary.

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were submitted in response

to the proposal or the FAA’s

determination of the cost to the public.

Conclusion

The FAA has determined that air

safety and the public interest require the

adoption of the rule as proposed.

Cost Impact

The FAA estimates that 50 airplanes

of U.S. registry will be affected by this

AD, that it will take approximately 1

work hour per airplane to accomplish

the required inspection, and that the

average labor rate is $60 per work hour.

Based on these figures, the cost impact

of the inspection required by this AD on

U.S. operators is estimated to be $3,000,

or $60 per airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the requirements of this AD action, and

that no operator would accomplish

those actions in the future if this AD

were not adopted.

Regulatory Impact

The regulations adopted herein will

not have substantial direct effects on the

States, on the relationship between the

national government and the States, or

on the distribution of power and

responsibilities among the various

levels of government. Therefore, in

accordance with Executive Order 12612,

it is determined that this final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

For the reasons discussed above, I

certify that this action (1) is not a

‘‘significant regulatory action’’ under

Executive Order 12866; (2) is not a

‘‘significant rule’’ under DOT

Regulatory Policies and Procedures (44

FR 11034, February 26, 1979); and (3)

will not have a significant economic

impact, positive or negative, on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act. A final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ADDRESSES.

further flight, remove the NLG shock

absorber and replace it with a new or

serviceable part, in accordance with the

service bulletin.

Airworthiness Directives; Airbus Model

A300, A310, A300–600 Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Airbus Model

A300, A310, and A300–600 series

airplanes. This amendment requires a

one-time operational test and repetitive

functional tests of the free fall control

mechanism of the landing gear to ensure

proper release of the main landing gear

(MLG), and corrective action, if

necessary. This amendment also

requires eventual modification of the

free fall control mechanism of the

landing gear, which constitutes

terminating action for the repetitive

functional tests. This amendment is

prompted by issuance of mandatory

continuing airworthiness information by

a foreign civil airworthiness authority.

The actions specified by this AD are

intended to prevent malfunction of the

free fall control mechanism of the

landing gear, which could result in the

inability to extend the MLG in the event

of failure of the hydraulic extension

system.

DATES: Effective August 12, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of August 12,

1998.

ADDRESSES: The service information

referenced in this AD may be obtained

from Airbus Industrie, 1 Rond Point

Maurice Bellonte, 31707 Blagnac Cedex,

France. This information may be

examined at the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, Rules Docket,

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were submitted in response

to the proposal or the FAA’s

determination of the cost to the public.

Conclusion

The FAA has determined that air

safety and the public interest require the

adoption of the rule as proposed.

Cost Impact

The FAA estimates that 24 Model

A300 series airplanes, 41 Model A310

series airplanes, and 61 Model A300–

600 series airplanes of U.S. registry will

be affected by this AD.

It will take approximately 3 work

hours per airplane to accomplish the

required operational test, at an average

labor rate of $60 per work hour. Based

on these figures, the cost impact of the

required operational test on U.S.

operators is estimated to be $22,680, or

$180 per airplane.

It will take approximately 2 work

hours per airplane to accomplish the

required functional test, at an average

labor rate of $60 per work hour. Based

on these figures, the cost impact of the

required functional test on U.S.

operators is estimated to be $15,120, or

$120 per airplane, per test cycle.

It will take approximately 26 work

hours per airplane to accomplish the

required modification on the Model

A300 and A300–600 series airplanes, at

an average labor rate of $60 per work

hour. Required parts will cost
